Ya, I gave up too. milled the caps shorter cause wouldn't seal against bladder. Then the shock rod would puncture bladder causing leaks. I would stick with stock caps, I've screwed around with these caps enough.

Yeah I've already sent them a message asking a few extra questions. Regardless of the reply, actual installation will have to wait 'till 3/4 because with Christmas and New Year my packages from eBay and AMain have been slightly delayed

Oh, I bought everything at the beginning of December, but it obviously wasn't enough, considering I live in Europe and had to get everything from American shops. Even including shipping and taxes it's STILL cheaper to do that than shop locally.

In other news, just got a reply from GH. That's right, only a few hours before New Year. That's dedication

To setup the shock, slowly fill the shock bodies, and slowly work out the
air bubbles prior to putting the cap on. The reason why our shock caps
don't have a bleed hole is because it makes more air bubbles in the
shocks.
As for the o-ring, the same one used in the stock caps .

HR spring retainers and shock ends are much higher quality than those from GH. Now, on the subject of shock caps..

I am a little dumbfounded, to be perfectly honest. HR shock caps do indeed have a bleeding hole. BUT! The whole is on the top of the cap (not the side like the stock shock caps), and there is nothing to close it with. It's simply a hole drilled through the whole cap. I'm not really sure what the intention was with this product, because I can't think of anything that would prevent ALL shock oil from simply leaking out.

Either I'm missing something incredibly obvious, or this is the biggest design flaw I've seen in an RC product since that one axle carrier I once bought for Kyosho Inferno that didn't have bearing cutouts.

i used these caps on all 4 shocks and 1 jump and blew all the bladders.you have to deburr the inside of the shock caps and put a piece of foam between the shock cap and the bladder.what happens is when the shock is compressed it forces the bladder into the hole in the top and causes them to rip.since i did the deburring and foam( like that comes in lipo battery boxes) i have no more problems out of them

The hole is a breather hole.. assemble the shocks & cycle, you can feel the air being pushed out...

Have any pic of all the parts, caps, O'rings etc......

Will post some pics tomorrow. I've assembled the shocks (using GH caps for now) , but I suspect there is some leakage even in their current idle state. I want to just leave them lying overnight and see what happens.

Could you please elaborate? What do you mean by "deburr"? What foam do you use, is that a Traxxas part?

i took a drill bit slightly bigger then the hole and just used my fingers to turn it then i took foam out of a battery box i got and cut it down to size and put in between the shock cap and the blue bladder.i do have to say sorry for taking soooooooo long to get back on here

I still don't quite understand exactly what it is you drill.

More pics: assembled and installed shocks + HR rockers + Tekno sways. Standard Traxxas 3x15 screws that connect push rods to rockers are too long for HR aluminium rockers, so I had to install some washers. But this is only a temporary measure, I imagine I'll have to order some 3x12 or 3x13 buttonheads from Tonys.

the inside of the shock cap.they way mine seemed was they drilled the hole from the top of the cap down and it left burs on the inside of the caps breather hole so i just removed them and made sure it was smooth

Ah, I get it now. Question though, Since the bleeding holes are made to let excess oil escape, what purpose to they serve if you put a piece of foam between the holes and the bladder?

In other news, one of my shocks still leaks, despite foam and teflon tape. I'll have to take it apart, inspect the bladder, replace the foam and add a few more layers of teflon tape to be sure.
